Question

The graph of the linear function f is shown in the ayplane above. The graph of the inear function g inot shown is perpendicular to the graph of fand passes through the point (1.-5) what is the value of g(-2) ?

Answer 1

Explanation:

slope of f(x) is 1/3 as y increases one unit for every three units increase in x.

Perpendicular lines have negative reciprocal slopes, so g(x) has a slope of -3

-5 = -3(1) + b

b = -2

g(x) = -3x - 2

g(-2) = -3(-2) - 2 = 4
